Reddit has been experimenting with a similar tipping bot that allows users to reward quality comment and posts. The Bitcointip bot was created by Reddit user NerdfighterSean last fall and has been used to tip more than $1,000 worth of Bitcoins across 1,542 transactions. The average tip has been $.65.

NerdfighterSean's service has been used to tip the likes of former New Mexico Gov. Gary Johnson, Bill Gates, and Rick Falkvinge, founder of the Swedish Pirate Party. Yearwood's Twitter Bitcoin Tipper, on the other hand, has already netted Obama .4 Bitcoins (which, according to current conversion rates, is about $18.96).

If being able to buy pizza, electronics, and blogging features using Bitcoins wasn't enough to convince you that the digital currency had finally hit its stride, Reddit's Bitcointip bot may be enough to win you over.
